The actuator must be dismantled and the elements sorted into various material groups before disposal.

Before disassembly please contact Danfoss support for disassembly instructions.

Disposal

Complete the mechanical and electrical installation (see instructions) and perform the necessary checks and tests:

- Turn on the power- Set the appropriate control signal and check

that the valve stem direction is correct for the application.

The unit is now fully commissioned.

Commissioning

Technical data

Please check power supply and power consumption prior connection!

Installation

Design

1. Manual operation knob 2. Function buttons 3. Service cover 4. Removable gland support 5. End position indication ring 6. Stem connector 7. Valve connector (yoke)

Mechanical Please check the allowed installation positions for the valve and actuator. The actuator can be installed in all positions (see below).

Use a M8/SW13 key (not supplied) to fit the actuator to the valve body. Allow for necessary clearance for maintenance purposes. To link valve and actuator stems use a 4mm Allen key (not supplied). The actuator has position indication rings which should be pushed together before el. connection; after self-stroking they indicate end positions of the stroke.

Electrical connection Electrical connections can be accessed by removing the service cover.

Four cable entries are provided for M 16×1,5 or M 20×1,5 cable glands. Note that in order to maintain the enclosure’s IP rating, appropriate cable glands must be used.

LED operating mode indicatorThe three-colour (green/yellow/red) LED function indicators are located on the actuator cover. They indicate different operating modes.

RESET button (versions AMV 658)Actuators AMV 658 have external RESET button which is located on top cover of the actuator next to LED indicators. With this button you can enter or exit Stand-By mode (press once) See next paragraph for mode details.

Operating modes• Stand-By mode (versions AMV 658)

Press the RESET button for 1 sec. to enter Stand-By mode. The actuator stops in current position and stops responding to any control signal. Red light is constantly lit. You can manually operate the actuator with mechanical handle (version AMV 655/658) or control buttons (versions AMV 658). This mode can be very useful during the commissioning of other equipment, or for service purposes. To exit Stand-By mode press the RESET button again.

• Positioning mode The actuator is operating automatically. The stem is extending or retracting according to the control signal. When positioning is finished the actuator goes to Stationary mode.

• Stationary mode The actuator is operating without errors.

• Error mode Working temperature is too high - check the ambient temperature.

Stroke is too short - check the connection with valve and valve operation or check if valve is blocked.

LED indication for AMV 655/658

NOTE! LED signalling is a direct indicator of the signal from controller therefore lengths of LED indication can vary and sometimes even look like a short flash if the controlling signal is present for a very short period.

Actuator type AMV 655 doesn’t have constant power supply and operates only when the controller provides a signal. Therefore limited LED indication possibilities are available.

DIP switch setting The actuator has a selection of DIP switches (Fig. 1) under the service cover.

DIP1: FAST/SLOW – Speed selection - FAST; 2 s/mm- SLOW; 6 s/mm

DIP2: DIR/INV – Direct or inverse actingselector (Fig. 2):- DIR position; the actuator is direct acting to

input signal.- INV position; the actuator is (reverse) inverse

acting to input signal.

Actuator type Mechanical operation

Electrical operation

AMV 655

AMV 658 The actuator AMV 655 can be manually positioned and remains in selected position until it receives signal from the controller.The actuator AMV 658 can be manually positioned when in Stand-By mode or when there is no power supply (mechanically).

Mechanical manual operationActuators AMV 655/658 have a knob & crank on the top of the housing which enables hand positioning of the actuator.

Use Mechanical manual operation only when the power is disconnected.

Electrical manual operationThe actuator AMV 658 has two buttons on the top of the housing that are used for electrical manual positioning (up or down) if the actuator is in Stand-By mode. First press the RESET button until the actuator goes to Stand-By mode (red LED is lit). By pressing the upper button the stem will be extending and by pressing the lower button the stem will be retracted.

Mechanical and electrical operation are not allowed to be used at the same time!
